Background

Dr. Jacob Whipple had built a thriving solo practice but found himself constrained by the demands of managing every aspect of the business. He wanted to expand his services, invest in continuing education, and reach more patients — yet lacked the time, resources, and support to do it effectively. When his practice became part of Cornerstone, which later partnered with P1 Dental Partners, Dr. Whipple saw the opportunity to achieve sustainable growth while maintaining his focus on patient care.

Approach

Through P1’s partnership model, Dr. Whipple gained access to expert operational support, CE programs for himself and his team, and a collaborative network of like-minded providers. With P1’s guidance, he also identified and integrated nearby practices from doctors preparing to retire — bringing in new patients while preserving the trusted continuity of care those practices had established.

Results

The practice experienced significant growth, both clinically and operationally. With the addition of advanced equipment such as a CBCT scanner, Dr. Whipple enhanced diagnostic accuracy and expanded into implant dentistry. Continued investment in CE opportunities has allowed him and his team to broaden their skills and offer more advanced, comprehensive care to their patients. Freed from day-to-day administrative burdens, Dr. Whipple can focus on what he values most — delivering exceptional care and leading his team to new levels of excellence.

“Partnering with P1 has allowed me to grow in ways I never could have on my own. We’ve expanded our services, welcomed new patients, and built a stronger, more resilient practice for the future.”

Background

Dr. Brent Sonner built a thriving, patient-focused practice known for quality care and a strong community reputation. When he partnered with P1 Dental Partners, the goal wasn’t to fix what wasn’t working—it was to elevate an already successful operation by introducing standardized systems, modern technology, and data-driven tools that could support continued growth.

Challenge

Like many established practices, day-to-day operations had evolved organically over time. Without consistent systems or shared technology, it was difficult to capture efficiencies or scale best practices across the team. Dr. Sonner and his office manager, Cassidy Brown, saw an opportunity to strengthen their processes and set the practice up for sustainable long-term success.

Solution

With support from P1 Dental Partners, Dr. Sonner and Cassidy led a proactive transition to streamlined systems and standardized workflows. Together, they implemented scheduling and billing SOPs, adopted new technology platforms, and created team dashboards to track performance and share wins. Their shared leadership and willingness to embrace change quickly set the tone for the rest of the team.

Impact

The results have been clear: new-patient growth, stronger revenue performance, and improved margin efficiency—all while maintaining the same high level of patient care. The enhanced systems have freed the team to focus on what matters most: providing exceptional experiences and building long-term patient relationships.

“Cassidy and I have always worked well together, and partnering with P1 gave us the tools and structure to take things to the next level. We feel more efficient, more supported, and more confident about the future.”

Background

Dr. Andy Koultourides has built one of his community’s most respected dental practices—known for high-end services, clinical excellence, and long-standing patient relationships. With an established associate and a dedicated clinical team, the practice continued to thrive post-COVID, but Dr. Koultourides recognized the need for stronger operational leadership to match the practice’s high standards and continued growth.

Challenge

While the clinical side of the practice was exceptional, the evolving post-COVID environment brought new challenges in staffing, systems, and team alignment. Dr. Koultourides knew that having the right office manager would be key to sustaining the practice’s positive culture and ensuring long-term stability.

Solution

Through P1 Dental Partners, Dr. Koultourides found that leadership partner in Robert Mengel, an experienced office manager who brought fresh energy, structure, and accountability to the practice. With P1’s recruiting support and onboarding resources, Robert was able to quickly build rapport with the team, streamline processes, and help reestablish a culture of collaboration and consistency.

Impact

The results have been powerful: a reinvigorated team culture, renewed energy in the office, and a stable foundation for continued success. With strong leadership in place, Dr. Koultourides can focus on what he does best—delivering exceptional care to his patients—while knowing the practice is running smoothly and positioned for the future.

“Robert has brought incredible stability and leadership to our team. The culture feels refreshed, our systems are stronger, and I have the confidence to focus fully on patient care.”

Background

Dr. Michael Pitt was among P1 Dental Partners’ original partner doctors — an experienced clinician with a loyal patient following and a thriving practice. When Dr. David Hazelrigg joined P1 in 2022, he brought both a modern facility and the ambition to continue growing his practice. Together, the doctors saw an opportunity to strengthen access to care and build something greater — by combining their practices and expanding their shared space.

Challenge

When you join two successful practices into one, there’s always a little trepidation. Will the teams be able to mesh? Will one doctor need to change the way he practices? Can the administrative staff seamlessly integrate different systems and protocols? Those questions—and many more—were front of mind for both doctors. Dr. Pitt’s long-established office had reached its capacity, limiting patient access and future growth, while Dr. Hazelrigg had the physical space but had not yet built out additional operatories. Growth would require investment in infrastructure, technology, and a shared vision for the future.

Solution

Fortunately, both Dr. Hazelrigg and Dr. Pitt have always led with a patient-first mentality and surrounded themselves with outstanding teams. With support from P1 Dental Partners’ operations team, the practices were successfully merged under one roof. P1 facilitated the design and buildout of new operatories, equipped the expanded facility with state-of-the-art technology, and helped integrate systems and staff across both teams. The process wasn’t always easy or seamless, but collaboration, communication, and P1’s hands-on guidance made all the difference.

Impact

The unified practice is now stronger than ever. Patients benefit from expanded access, advanced technology, and a cohesive team committed to clinical excellence. The doctors and team members enjoy renewed collaboration and energy. For Dr. Pitt, the transition allowed him to step back from administrative responsibilities and focus fully on patient care—reigniting his passion for dentistry. For Dr. Hazelrigg, the expansion provided the space, structure, and support to continue growing for years to come. And for both, the experience reinforced a simple truth: when you have a great team, everything else falls into place.

“P1’s support allowed us to bring two great practices together and create something even better. We have the technology, space, and structure to grow—and the team to make it all work.”

Background

In August 2023, Dr. Doreen Wascow joined P1 Dental Partners, bringing her long-standing practice into the organization. By coincidence, another P1 partner practice — led by Dr. Caroline Shepherd and Dr. Ashley Watson — operated on the first floor of the very same building in the northern suburb of Chicago, Mundelein. What began as two distinct offices has evolved into a collaborative, thriving example of how integration can elevate patient care and team performance.

Approach

Rather than operate independently, both teams leaned into the spirit of partnership that defines P1. The doctors and staff began sharing knowledge, resources, and ideas — from clinical protocols to front-office workflows. The front desk teams communicate daily, coordinating schedules, sharing learnings in practice management tools, and helping one another navigate new efficiencies.

Dr. Shepherd shared, “I’ve appreciated Dr. Wascow’s advice on running a practice. Our front desk staff communicates daily, which has been helpful with showing each other all the different Ascend features. We’ve also been able to share clinical staff and materials, which has made both teams stronger.”

Upstairs, Dr. Wascow and Dr. Shena Patel have built a seamless partnership focused on clinical quality and patient experience. Downstairs, Dr. Shepherd and Dr. Watson continue to model collaboration in every aspect of their work — proving that great outcomes come from great teamwork.

Results

The integration of the two practices has led to stronger communication, more efficient operations, and a shared commitment to patient-first care. Each team retains its own personality, but together they embody the best of what P1 represents: practices united by common purpose.

As Dr. Wascow notes, “Working side-by-side with another P1 practice has been such a positive experience. We’ve built real connections — supporting each other, sharing resources, and creating a better experience for our patients and teams.”

“Collaboration has truly made both practices better. When you share ideas and help each other succeed, everyone wins — especially the patients.”
